RDP kubutaka bwumye

Amashanyarazi avanze yumye nubwoko bwa granular na powdery bivanze nibintu byiza hamwe na sima ya sima idasanzwe, ibikoresho bigumana amazi, ibikoresho bigabanya amazi, imiti igabanya ubukana, imiti igabanya ubukana hamwe nibindi byongeweho bivanze neza muburyo runaka. Ijyanwa ahabigenewe ikamyo idasanzwe cyangwa igikapu gifunze amazi adafunze, hanyuma kivangwa namazi. Noneho usibye sima n'umucanga mumubare munini wa minisiteri yumye ivanze, ubwinshi bwibindi ntibisubirwamo.ifu ya polymer RDP. Kubera igiciro cyacyo kinini kandi kigira ingaruka zikomeye kumitungo ya minisiteri, nicyo abantu bibandaho. Ingaruka zo kugarurwaifu ya polymer RDPku miterere ya minisiteri yaganiriweho muri iyi nyandiko.

Uburyo bwo Kwipimisha

Kugirango umenye ingaruka za redispersibleifu ya polymer RDPibikubiye kumiterere ya polymer mortar, Amatsinda menshi yubushakashatsi yateguwe nuburyo bwikizamini cya orthogonal kandi yapimwe hakurikijwe dbjoi-63-2002, ubuziranenge bwubugenzuzi bwa polymer Mortar kugirango butangwe hanze yurukuta rwinyuma, kugirango hamenyekane ingaruka za polymer minomeri kuri tensile imbaraga zubusabane, gukomeretsa gukata imbaraga nimbaraga zo guhonyora, imbaraga zingirakamaro hamwe nigipimo cyimiterere ya polymer mortar kuri beto.

Ibikoresho nyamukuru ni P-04 2.5-pu silicon sima; RE5044 na R1551Z birashobora kongera gutatanya no kongera gutatanya ifu ya emulsion; 70-140 mesh quartz umucanga; Ibindi byongeweho.

2 Ingaruka zo kugarurwaifu ya polymer RDPkumiterere ya polymer mortar

2.1 Inkunga ya Tensile na compression shear bond imitungo

Hamwe no kwiyongera kwa redispersibleifu ya polymer RDPibirimo, imbaraga zingirakamaro zingirakamaro hamwe na compressive shear bond imbaraga za polymer mortar na sima minisiteri nayo iriyongera, kandi imirongo itanu irazamuka ugereranije no kwiyongera kwa sima. Ingingo zose zingirakamaro zipima impuzandengo, ariko isesengura ryinshi rirashobora gutatanyirizwa ifu ya emulsiyumu kurwego rwingaruka zimikorere ya sima ya sima irashobora kubona ko hamwe niyongera ryibintu byongeye gukoreshwa byifu ya emulsiyumu ku guhuza imbaraga za sima, polymer mortar compressive shear strength icyerekezo cyo gukura kumurongo, icyerekezo rusange cyo kwiyongera 1% kugirango gitatanyeifu ya polymer RDP, imbaraga zo guhuza ziyongereyeho 0.2 MPa, Imbaraga zo guhuza inkweto ziyongereyeho 0.45MPA.

2.2 Kwikuramo / kugonda ibintu bya minisiteri ubwayo

Hamwe no kwiyongera kwibirimo byo kugarurwaifu ya polymer RDP, imbaraga zo guhonyora hamwe nimbaraga za flexural ya minisiteri igabanuka, byerekana ko polymer igira ingaruka zibangamira hydrata ya sima. FIG. 4 yerekana ingaruka za redispersibleifu ya polymer RDPibikubiye kuri compression no kugabanura igipimo cya polymer mortar. , hamwe no kwiyongera kwibirimo byo kugarurwaifu ya polymer RDP, igipimo cyo kwikuramo igipimo cya polymer mortar kigabanuka, byerekana ko polymer itezimbere ubukana bwa minisiteri. Ingaruka yibirimo byo kugarurwaifu ya polymer RDPku mikorere ya polymer mortar irashobora gusesengurwa muburyo bugereranije nuburemere buringaniye bwa buri ngingo. Hamwe no kwiyongera kwibirimo byo kugarurwaifu ya polymer RDP, imbaraga zo guhonyora, imbaraga zingirakamaro hamwe nigipimo cyimiterere ya polymer mortar yerekana umurongo ugabanuka. Imbaraga zo guhonyora, imbaraga zingirakamaro hamwe nigipimo cyimiterere ya redispersibleifu ya polymer RDPyagabanutseho 1.21 MPa, 0.14MPa na 0.18 kuri 1%. Birashobora kandi kugaragara ko kubera kwiyongera kwinshi kugarurwaifu ya polymer RDP, imiterere ya minisiteri yarahinduwe.

2.3 Isesengura ryinshi ryerekana ingaruka za sima-umucanga ku miterere ya polymer mortar

Muri polymer mortar, igipimo cya sima-umucanga kandi ntigisubirwamoifu ya polymer RDPibirimo bikorana muburyo butaziguye, birakenewe rero kuganira ku ngaruka ziterwa na sima-umucanga ukwayo. Ukurikije uburyo bwa orthogonal igerageza uburyo bwo gutunganya amakuru bizaba bitandukanye cyane nkibihinduka, gutatanya birashobora guhuzwa naifu ya polymer RDPibirimo nkibintu bihoraho byerekana itandukaniro ryingaruka zimpinduka kumibare yububiko bwa minisiteri, irashobora kubona ko hamwe no kwiyongera kwinyuranyo kumikorere ya sima ya minisiteri ya minisiteri ya polymer na polymer mortar ubwayo igenda igabanuka cyane, Icyerekezo rusange ni uko imbaraga zingirakamaro za polymer mortar kuri sima ya minisiteri igabanukaho 0.12MPa, imbaraga zo guhuza inkweto zo kugabanuka zigabanukaho 0.37MPa, imbaraga zo gukomeretsa za polymer mortar zigabanukaho 4.14MPa, imbaraga za flexural zigabanuka na 0,72MPa, naho igipimo cya flexural kigabanukaho 0.270 hamwe na buri kwiyongera kwa sima-umucanga

3 Ingaruka zo kugarurwaifu ya polymer RDPku guhuza kwinshi hagati ya polymer mortar na EPS foam polystyrene ikibaho DB JoI-63-2002 yerekana ko guhuza minisiteri ya polymer na sima na sima ya EPS bivuguruzanya.

Iyambere isaba polymer mortar kugirango ikomere, mugihe iyanyuma isaba guhinduka kwayo kuba hejuru, ariko urebye injeniyeri yo hanze ikomeza gukomera kurukuta rukomeye hamwe nubuyobozi bwa EPS bworoshye, icyarimwe kugirango harebwe niba ibiciro bitari hejuru cyane. Kubwibyo, ingaruka zibiri muri redispersibleifu ya polymer RDPku buryo bworoshye guhuza imitungo ya polymer mortar yashyizwe kurutonde kugirango ushimangire akamaro kayo.

4Ingaruka zubwoko bwa redispersibleifu ya polymer RDPku mbaraga zo guhuza ubuyobozi bwa EPS

R5, C1, P23 ubwoko bwa redispersibleifu ya polymer RDPbatoranijwe mu mahanga. Tayiwani D2, D4 ubwoko 2; Imbere mu Gihugu S1, S2 2 amoko 7; Ikibaho cya polystirene cyakozwe i Beijing 18kg / umurongo wa EPS. Ukurikije ibipimo bya dbJ01-63-2002, umurongo urambuye ushobora kugarurwaifu ya polymer RDPy'Inama ya EPS irashobora kuzuza ibisabwa kandi byoroshye guhuza imikorere ya polymer mortar icyarimwe.
